Used ULVAC DA-20D #9243382 for sale

ULVAC DA-20D is a double stage dry pump designed for use in a variety of industrial applications. It utilizes direct-drive motors and is equipped with two stages of rotary vane pumps that create an absolute pressure of 2.0 Torr and vacuum to 10-4 Torr. The first stage creates an outlet foreline pressure of 40-100 Torr, while the second stage rotary pumps the remainder of the air down to 10-4 Torr. The motor for the dual stage pump is a ULVAC 10 HP motor with adjustable speed, stepless control, overload protection and a hi-efficiency impeller. The motor also provides fast response, low vibration and noise levels, and a wide operating and safe operating temperature range. DA-20D gas ballast feature allows contaminants like H2O, C2H2, etc. to be absorbed by the pump before entering the outlet foreline, which prevents these corrosive elements from entering the equipment. Its oil circulation system features a constant oil flow to minimize oil degradation, which extends the life of the oil and helps to improve overall pump efficiency. In terms of safety, ULVAC DA-20D is equipped with a plumble pressure switch and an emergency shutoff switch that prevents the pump from overheating while under operation. Additionally, the motor features an insulation and overcurrent protection unit which will shut down the pump in the event of an overcurrent or overheat condition. DA-20D is a reliable and durable dry pump that is perfect for industrial applications that require vacuum and high absolute pressure. With its direct-drive motor, reliable oil circulation machine, and gas ballast feature, it is sure to provide a safe and efficient transfer of air particles. Its low vibration and noise make it ideal for use in environments that require silence.
